Controller 120 is set as accepting the detection signal of self-detector 68, and as described later, the signal of each parts action is controlled in output.

Label 1 is groove forming part, forms identically with the first embodiment, between position of readiness and progressive position, moves, and in Figure 12, only with double dot dash line, represents the state in position of readiness.

As original state, make as described below in advance each parts action.

That is, make the 4th servomotor 92 actions, make in advance the first erecting bed 88 move to position shown in Figure 12 (following, to be called " original position ") standby.

Again, make each self-corresponding cylinder action, make in advance the second arm 58, the 4th support unit 98 and the 5th support unit 106 move to position shown in Figure 12 (following, to be called equally " original position ") standby.

Have, groove forming part 1 is also identical with the first embodiment again, moves in advance position of readiness standby.

On the other hand, make the second cylinder 48 make backward movement, make the second support unit 80 move to primary importance standby.

If the end, second direction downstream (following, to note by abridging as " downstream ") of transported sheet material 62 detected by detector 68, this detection signal is sent to above-mentioned controller 120.

So controller 120 sends stop signal to the 3rd servomotor 66 at first, as shown in figure 12, in the end of downstream side of sheet material 62, be positioned at the position of the groove 81a of the second support unit 80, roller 64 is stopped.

Again, receive the controller 120 of the detection signal being sent by detector 68, also to the second servomotor 18, send signal simultaneously, identical with the first embodiment, make cutting knife 3 revolutions of groove forming part 1.

Then, for roller 64 is stopped, after the sufficient time, controller 120 is identical with occasion shown in Fig. 3, makes each the 3rd cylinder 60 make backward movement, identical with the first embodiment, make each the second arm 58 revolutions, make sharp keen front end and the surperficial crimping of sheet material 62 of each limiting part 50.

After this, controller 120 sends the signal that makes the 5th cylinder 112 action, and the 3rd arm 107 is declined, and as shown in figure 15, the tabular surface 108a by the second push part 108 is pressed on the downside end of sheet material 62 on the second support unit 80.

Then, make two first servomotor 15 actions, make the synchronous forward of two screw rods 10.

Its result, groove forming part 1, along incline direction as shown in Figure 16 arrow, moves towards the progressive position dotting from position of readiness.

In addition, start simultaneously with the above-mentioned mobile of groove forming part 1, by the 4th servomotor 92, screw rod 90 is just being turned round, make the first erecting bed 88 along second direction shown in Figure 16 arrow, on one side the interval along second direction with groove forming part 1 is kept to certain mobile on one side.

The tabular surface 108a of the 3rd arm 107 moving towards second direction with the first erecting bed 88 one and inclined plane 108b as shown in figure 16, in second direction, become until the shape in groove forming part 1 downstream.

Thus, when the cutting knife 3 by groove forming part 1 is cut before the end of getting sheet material 62, by the second push part 108, make in advance this end be pressed on the second support unit 80.

If the downside front end of the second push part 108 arrives the ratio sheet material 62 low some lower side position in end (following, to be called " the 3rd position ") as shown in figure 16, the 4th servomotor 92 stops the just revolution of screw rod 90, stops the movement of the first erecting bed 88.

On the other hand, make two first servomotors 15 continue revolution, if groove forming part 1 arrives position shown in Figure 16 dotted line, stop this revolution.

Its result, identical with the first embodiment, even if there is Local warping the above-mentioned end of sheet material 62, also can correct as smooth, under this state, by cutting knife 3, cut the end of getting sheet material 62.

So, on sheet material 62, identical with Fig. 8 of the first embodiment, with spacing 2T, form the first groove 62a, the width of the first direction of this first groove 62a is T, at the cross sectional shape with incline direction vertical direction, is V word shape.

When groove forming part 1 moves, each cutting knife 3 moves between each the 3rd arm 107 of adjacency, and therefore, each the 3rd arm 107 can not harm movement.

Again, groove forming part 1 is in progressive position standby.

If form above-mentioned the first groove 62a, through the sufficient time, controller 120 output signals make each parts action by the following stated.

That is, make the piston rod 112a of each the 5th cylinder 112 make backward movement, make the second arm 108 rise to position shown in Figure 17.

Then, make the piston rod 102b forward motion of four-cylinder 102, be projected into maximum.

So the 4th support unit 98 turns round centered by the 3rd bolster 100, as shown in figure 18, relative the first erecting bed 88, tilts the 4th support unit 98.At this moment, downside front end and the sheet material 62 of setting the second arm 108 do not touch and connect, even if touch, connect, as mentioned above, and limiting part 50 and sheet material 62 crimping, therefore, sheet material 62 can not be offset by relative the first erecting bed 88.

On the other hand, the second arm 108 resets to shown in Figure 17 behind position, makes the second cylinder 48 make forward motion, makes the second support unit 80 displacement T, in second place standby.

Even in this moves, also identical with the first embodiment, due to limiting part 50 and sheet material 62 crimping, therefore, can not change the position of relative the second support unit 80, one moves.

Then, by the 4th servomotor 92, screw rod 90 is just being turned round, make the first erecting bed 88 be positioned at position shown in Figure 19,, each first groove 62a of sheet material 62 become each second push part 108 under position (following, to be called " the 4th position ").

Then, if by the forward motion of the 5th cylinder 112, the second push part 108 is declined, as shown in figure 20, shown in each inclined plane 108b of the second push part 108 and Figure 11 of the first embodiment, occasion is identical, compresses each first groove 62a, same, even if there is Local warping the above-mentioned end of sheet material 62, also can correct as smooth.

Then, from controller 120 output signals, make two first servomotor 15 actions, make two screw rods 10 synchronous reversions.

Its result, groove forming part 1 as shown in figure 21, moves to the position of readiness representing with double dot dash line from progressive position.

Thus, the downside end of sheet material 62 is cut and is got by cutting knife 3, identical with Fig. 9 shown in the first embodiment at sheet material 62, with spacing 2T, forms the second groove 62c, and the width of the first direction of this second groove 62c is T, at the cross sectional shape with incline direction vertical direction, is V word shape.

That is, in this forms, identical with the first embodiment, at the downside end of sheet material 62, form the first groove 62a identical, roughly homogeneous shape and the second groove 62c separately.

When this groove forming part 1 moves, each cutting knife 3 moves between each the 3rd arm 107 of adjacency, and therefore, each the 3rd arm 107 can not harm this yet and move.

As mentioned above, in the first embodiment or the second embodiment, by bonding agent, be built up between the sheet material 62 of the first groove 62a and the second groove 62c, make not form in the end of a sheet material above-mentioned the first groove 62a and the second groove 62c engagement of above-mentioned the first groove 62a and the second groove 62c place and another sheet material, make adhesive hardens.
